useful Improvements in Seals for Bottles, of

which the following is a specification.

It is the object of the invention to rovide an improvement in sealing means or the style the lpurpose being to prevent the escape of the iquid and the gases contained in the liqr'event contact between the packing materia of which the sealing means is comosed and the liquid, which may be detrimentalto both, to prevent the liquid, or'tl e;

I gases from reaching the metallic cap, and to mg the coinpressib e prevent the liquid or gases uid andgaseslrom reachsubstance comprised 111 revent also the ii the seal.

The invention is disclosed in its broad and essential features in application for Letters Patent of the United States, filed September 10, 1901, Serial No. 74,899, Renewal '0.

bottle-closure known as the Crownfl tending flange 6. In the groove 8, frmcd The seal is in the form of a washer composed partly of compressible material an partly of metal, the metal being adapted to 1nd a hearing about the bottle-mouth and sible material from coming in contact with each other, which would deletcriously affect both the material and the liquid.

The invention consists in the features and combination and arrangement of arts here inafter described, and particulary pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional view of a bottle and crown with the seal associated therewith. Fig. 2 is a sectional view of thesealing' means separated from the crown. F'". 3 is a bottom plan view of the sealing ns.

In the drawings, l represents the bottle of well-known form having an exterior shoulder of the crown 3 is locked in any suitable "manner. The sealin medium comprises a disk 4 or lining of meta of a non corrosive character not to be afiected by or affect injuriously the conminium-and a ring of compressible material 5, such as rubber, textile material covered or saturated with rubber, or, cork or any suitable composition. This compressible material or packiniis held permanently by the aluminium dis or lining by being clamped between flanges or edges 6 7 on the said disk. The disk, with its two annular flanges, is formed all in one. piece and enerally of inverted-cu form, the flange 7 sing rovided by doub 'ng the sheet metal uponi self at the edge of the cup, from which point the metal is continued to orovide th side of the cup and then extends outwardly to form the groove y the two flanges, the ed e of the packing material is seated and is c amped firmly.

The arts of the sealing-washer or com plete disk as thus formed are of suchdiameter that the packin material will rest on the lip of the bottle, w ere it will be compressed by the pressure exer in a crown to the bottle. The meta c dis extending over the mouth of the bottle will also find a seat on the edge of the bottle-mouth by its flange 7 resting thereon, and the pressuie exerted in app ing and locking the crown in place forces t e ange of this metallic disk or cup hard u on the bottle lip or edge and founs a erfect c osure at this print, pro venti the 'qpid from reachin the compressib e ma erial and avoiding a danger of the liquid tasting of the rubber or other ma tsrial'oi which the asking maybe composed. The metallic dislr of non-corrosive material Eevents the liquid or gases from reschin the etallic crown. No collet of paraiiinei p:-

peror like material need be used with arm of closure as is disk 'packin o cork, as the metal prevents the liquid om reaching both thcpacking material and the metallic crown.

I claim- 1. A washer or seal for bottle-ca s comprising a. lining of su'table materia and a packing material of ring form attached thereto, substantially as described.

2. A, washer or seal for bottle-caps cornprisin a lining ofsuitable material and a ring of pac material attached thereto by a portion 0 the lining clamping the packing, substantially as described.

as completed is 8' and the outwardly-exlyi the found desirable with s.
